WebP vs AVIF vs SVG
How the three modern formats differ and which to use for photos, icons, and graphics.
Raster vs Vector
WebP and AVIF are raster formats with excellent compression for photos — AVIF usually smaller, WebP more widely supported. SVG is vector, unbeatable for logos, icons, and flat illustrations that must scale crisply.
- AVIF: best compression for photos
- WebP: great compression, broad support
- SVG: best for icons and scalable graphics
Picking by Content
Use AVIF or WebP for photographs and complex imagery; use SVG for anything line-based or logo-like. Many sites combine all three: AVIF/WebP for hero photos, SVG for UI and icons.
- Photos → AVIF first, WebP fallback
- Icons, logos, charts → SVG
- Mix formats per asset type for best results
